IMPROVED'` MODE OFNRAISING SUNKEN VESSELS.

Specification forming part of Letters Patent No. 37,0B, dated January 13, 1863.

T0 all whom it may concern:

Beit known that 1, FREDERIC KETTLER, of Milwaukee, State of Visconsin, have invented anew and Improved. Mode of Providing Fnstenin gs for Raisin g-Power on Sunken Vessels; and I do hereby declare that thefoll lowing is a full and exact description thereof', reference being had to the accompanying drawings, and to the letters ot' reference marked thereon, making a part oi this specification.

The nature ot' my invention consists in the construction ofthe screw (I and auger b in one piece, and the manner in which it is made to operate as afa-'stening on to the deck of a sunken vessehby the arrangement and combination of this sc1'e\\'auger with ropes 16, rodsl I and l2, teethc, puileys 14, and air-balloons for the purpose of raising sunken vessels.

Figures a., b, c, d, c, j', h, and l represent the different instruments as fastenings onto sunlien vessels. Fig. c, being one ot' these instruments, shall now be described.

11 is an iron rod making a part ofthe frame. Rod 12 is provided with a screw, an, and auger b. This auger b is hollow, similar topa spoon-bit, for the purpose of removing the chips produced by the operation thereof. The screw a is also hollow and surrounds the auger b, the chips passing upward through the inside of the. screw. The screw alturns in after the auger b and iirmly' secures the rod to the deck ot the sunken vessel. Aniron plate, 13, iorms the conjunction of rods 11 and ila-nd isl provided with teeth c, which take hold in the deck of sunken vessel, so as give the auger Z1 a firm hold on the same. 14 14 are pulleysto be operatedby means of rope 16, the ends of which are floated on the surfaceot' the water by means of balloons d. A ratchet, e, is attached to pulley f on rod 12, preventing the contrary motion ofthe auger a when operated by pullingthe ends of rope 16 up and down.

Said ratchet eis movable, it being intended i to slide ina furrow with which rod 12 is provided, as the auger advances into the deck. This ratchet eis plainly shown in sectional View of Fig. b. Rod 12 is also providedwith rin g g, to which the raising power may be attached. A balloon, d, is attached to rod`11 tor the purpose of keeping this instrument c in a perpendicular position when lowered on the. deck ot said vessel.

This machine is intended to operate on wood, or For light work in general.

To render this machine more substantial,

and thus make it tit for heavy Work, a conical wheel may be attached to the pulley 20 in Fig. d, which operates in conicd wheel 1S.

The instrument shown in Fig. Z is intended to operate on metal in case the vessel is plated, and is operated in the same manner as in the former. Y'

Figs. b, e,f, and It are instruments to heapplied and closed upon at different portions ot' the sunken vessel, and are closed up and sef cured to the same in the same manner and by means of the same arrangement and opera` tion and for the same purpose as by the former instrument c. Y

By means ot' these instruments all submarine or diving apparatus are dispensed with.

Wha-t l claim as my invention, and desire to secure by Let-ters Patent, is

1. Theconstruction otl the screw auger a b, as herein described.'

2. The screw-auger as combined with rods 11 and 12, plate 13, pulleys 14, ropes 16, teeth c, and balloons d, when arranged as herein specied, to form the instrument or machine c for raisingsunlien vessels.

FREDERIC KETTLER.
